Introduction to Python Programming

Question 1

program

Answer 1

A sequence of computer language statements that have been crafted to do something

Question 2

Ways a program gets its data; user input through the keyboard, mouse, or other device.

Question 3

Processing

Answer 3

Takes the data inputs and prompts and calculates the results (output).

Question 4

Output

Answer 4

The results at the end of a program based on user input and system processing.

Question 5

The ________ is the “grammar” rules of the programming language. Each programming language (like Python) has its own

Answer 5

Syntax

Question 6

A ________ scans an entire program and attempts to convert the whole program at once to machine code.

Answer 6

Compiler

Question 7

Also known as machine language. The computer uses binary (0s and 1s) to perform tasks. At a high level, the programming language code that you write gets translated or compiled to the machine code that the computer understands.

Answer 7

Machine Code

Question 8

An intermediary step for code conversion between the programming language that you write and the machine code that a computer uses.

Answer 8

Bytecode

Question 9

An __________ takes the bytecode one line at a time and converts it to machine code.

Answer 9

Interpreter

Question 10

Virtual Machine

Answer 10

A software program that behaves like a completely separate computer within an application.

Question 11

what are the steps for the development life cycle?

Answer 11

1. Understand what the problem being asked is.
2. Plan out the logic for the problem by breaking it down into a sequence of steps or algorithm.
3. Write the code to perform the algorithm.
4. Compile/translate the code to a format the computer can read.
5. Test the program to ensure there are no syntax or logical errors.
6. Deploy the program to be used.
7. Support the maintenance of the program.

Question 12

Which set of operations represents the correct order of a typical computer program?
a.) Output-Process-Input
b.) Input-Process-Output
c.) Input-Output-Process
d.) Process-Input-Output

Answer 12

b.) Input-Process-Output

Question 13

2. What are the grammar rules that define a programming language referred to as?
   a.) Machine code
   b.) Pseudocode
   c.) Syntax
   d.) Byte code

Answer 13

c.) Syntax

Question 14

3. Which term refers to the sequence of steps to solve a problem?
   a.) Interpreter
   b.) Machine code
   c.) Compiler
   d.) Algorithm

Answer 14

d.) Algorithm

Question 15

Variable

Answer 15

A named memory location that has the ability to hold various distinct values at different points in time in the program.

Question 16

Concatenate

Answer 16

combine words or numbers

Question 17

Pseudocode

Answer 17

English-like statements that describe the steps in a program or algorithm.

Question 18

String

Answer 18

A data type that can store a literal string as a value.

Question 19

Literal String

Answer 19

A series of characters that are combined together and enclosed in quotes; for example, “Enter in the second number” is a literal string.

Question 20

1. Which term refers to the English-like statements used to describe the steps in a program or algorithm?
   a.) Pseudocode
   b.) Source code
   c.) Program
   d.) Variable

Answer 20

a.) Pseudocode

Question 21

2. The first step in designing any program is to __________.
   a.) determine the program inputs
   b.) determine the purpose of the program
   c.) break down the problem into its smallest parts
   d.) determine the program outputs

Answer 21

b.) determine the purpose of the program

Question 22

3. __________ define(s) how steps should be arranged so that a program can complete a task correctly.
   a.) Logic
   b.) Pseudocode
   c.) Variables
   d.) Algorithm

Answer 22

a.) Logic

Question 23

Algorithm

Answer 23

A logical step-by-step plan that we need to build for solving a problem.

Question 24

Comments

Answer 24

The “#” (hashtag) is used in Python code to identify a comment. Commented lines of code are ignored by the compiler during run time. A programmer adds comments throughout the code to explain how the program or function works.

Question 25

Module

Answer 25

A self-contained piece of code that can be used in different programs.

Question 26

1. Why is it important to look for patterns when solving a problem and designing an algorithm?
   a.) Patterns reduce the number of steps it takes to get to a solution.
   b.) Patterns make the task more complex.
   c.) It is impossible to solve a problem without patterns.
   d.) Patterns increase the number of steps it takes to get to a solution.

Answer 26

a.) Patterns reduce the number of steps it takes to get to a solution.

Question 27

2. Algorithms consist of a(n) ____________ number of instructions.
   a.) abstract
   b.) finite
   c.) unlimited
   d.) approximate

Answer 27

b.) finite

Question 28

3. What should be considered first when designing an algorithm?
   a.) What are the inputs?
   b.) What are the decision types?
   c.) What are the order of the steps?
   d.) What are the outputs?

Answer 28

a.) What are the inputs?

Question 29

Integrated Development Environment (IDE)

Answer 29

A text editor that has additional functionality to allow developers to perform some additional tasks to simplify the workflow of the development process.

Question 30
